[commit: ghc] master: By default, use the dynamic way for programs in the GHC tree (b712667)

[Austin Seipp]

I ran into this earlier today. It's because your build.mk is now out of
date; just blow it away and copy the build.mk.sample file over again and
set your BuildFlavour.

However, the stage2 build will later fail because it doesn't think that
LLVM supports -fPIC and -fdynamic on ARM. The patch to fix this is simple
and it will unblock the build, but we'll need to do some work beyond that -
the fallout from using the combo dynamic/static way seems to have broken
some stuff (stage2 no longer builds with LLVM 3.2 for me...)

I will push shortly.
